Why do meteorologists never throw surprise parties?
Metrologists work very hard to keep time, using ever-finer technology to measure the passing of minutes, seconds, and hours. However, while their atomic clocks are incredibly accurate, they’re not perfect. No clock on Earth is entirely “correct”.
The actual process of defining what time it is – right now – is based on lots of clocks, all keeping time around the world. National laboratories all send their time-keeping to the International Bureau of Weights and Measures in Paris, which then creates a weighted average. Time, therefore, is a human construct.
Answer: Because despite their best efforts, they can never guarantee the timing
will be perfectly right! Isn’t that fascinating? #TimeKeeping
